1,4-Butanediol glycidyl ether, tseem hu ua 1,4-butanediol dialkyl ether lossis BDG, yog ib qho organic compound. Nws yog ib qho tsis muaj xim rau lub teeb daj kua nrog tsawg volatility. Nws yog soluble nyob rau hauv feem ntau cov organic solvents xws li ethanol, methanol thiab dimethylformamide. Feem ntau siv ua cov khoom siv tshuaj raw thiab cov kuab tshuaj. Nws kuj yog siv ua tus stabilizer rau dyes thiab pigments. Nws tuaj yeem tsim los ntawm esterification ntawm 1,4-butanediol nrog methanol lossis methanol kua. Cov xwm txheej tshuaj tiv thaiv feem ntau yog nqa tawm nyob rau hauv siab siab thiab nyob rau hauv lub xub ntiag ntawm ib tug catalyst.

Thaum siv 1,4-butanediol glycidyl ether, yuav tsum ceev faj kom tsis txhob raug rau daim tawv nqaij thiab qhov muag. Thaum siv thiab khaws cia, yuav tsum tsis txhob kub heev thiab qhov chaw hluav taws. Ua tib zoo saib xyuas qhov kaw ntawm cov thawv cia khoom kom tiv thaiv kev ua pa thiab xau.
